REE-0505S - RECOM Power

REE-0505S Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  A recommended PCB layout is to have a large copper area connected to the module's thermal pad, and to use thermal vias to dissipate heat to the bottom layer. This helps to reduce thermal resistance and improve overall thermal performance.
• How do I ensure reliable start-up of the module?
  To ensure reliable start-up, make sure to follow the recommended start-up sequence: apply input voltage, then enable the module by pulling the enable pin high. Also, ensure that the input voltage is within the specified range and that the module is properly decoupled.
• What is the maximum allowed capacitance on the output?
  The maximum allowed capacitance on the output is 47uF. Exceeding this value may cause instability or oscillation in the module.
• Can I use the REE-0505S in a high-temperature environment?
  While the REE-0505S is rated for operation up to 85°C, it's recommended to derate the output power at higher temperatures to ensure reliable operation. Consult the datasheet for derating curves and guidelines.
• How do I protect the module from input voltage transients?
  To protect the module from input voltage transients, use a TVS diode or a transient voltage suppressor in parallel with the input voltage. This helps to clamp voltage spikes and ensure reliable operation.
